Our invention relates to improvements in whiflietrees in which thetraces are secured to springs secured to the outer ends of the tree forthe purpose of relieving the traces of any ar.

The invention consists in the means for securing the springs in placeand a casing for protecting the springs and for guiding the same intheir movements.

In the drawings forminga part of this specification, Figure 1 representsa plan view of one end of our whiffletree, the construction of both endsbeing the same. Fig. 2 is a horii Fig. 3 is a zontal section through thesame. detail showing the spring.

Like reference-numerals indicate like parts in the views.

The whiffletree 1 is secured to the buggy by means of a bolt in theusual manner. Its outer ends 3 are tapered and flattened upon one side,as shown at i. Surrounding each of the tapering ends 3 of thewhifiletree is a cone-shaped sleeve 5, which fits tightly there on,leaving a space at its inner end between it and the flattened portion 4:of the whiffletree. Formed integrally with the sleeve 5 or securedthereto in any suitable manner is an angular-shaped casing 6, which hasan opening 7 at its inner end leading to the sleeve 5. Within the casing6, projecting through the opening 7 and lying in the space left betweenthe flattened portion 4. of the whiffletree and the inside of saidsleeve 5, is a bar 8, of spring metal, which is bent from the directionin which draft is applied and rests normally in a position along therear 5 the said springs are further protected ansHi guided by theangular-shaped casing 6.

Having thus described the invention, what is claimed as new is--Thecombination with a whiffietree having tapered outer ends, of acone-shaped sleeve fitting each end of said whiflietree, an angularcasing integral with or secured to said sleeve having an openingthereinto at its inner end and a bent bar of spring metal fitting saidcasing projecting through said opening and secured to the whiffletree bybolts passing through said sleeve, bar and tree, substantially as andfor the purpose described.
